OK got my Hypertech 52001 today and got it running. On the initial run it had codes P0930, B1633, B162B, B1421. I cleared those and programmed the XK. After the program I now have U0100, P0930, and U0431. I'm trying to find a list online with these codes but not having much luck. Oh is there any reason I would want to mess with my rev limiter or fan temp? I only changed it for regular gas and tire stuff right now.
